MACHINE FOR KNITTING HYDRAULIC HOSE, 80G.

SPECIFICATION forming part of Letters Patent No. 576,304, dated February 2, 1897'.

Application filed November 28, 1896. Serial No. 613,804. (No model.)

To ctZZ whom, .it may concer/t:

Be it known that I, WILLIAM EsTY, a citizen of the United States, residing at Laconia, in the county of Belknap and State of New Hampshire, have invented certain new and useful Improvements in Machines for Knitting Hydraulic I-Iose, &c., of which the following is a specification, reference being had therein `to the accompanying drawing.

The invention consists in an improved form of knitting mechanism, comprising a novel combination of parts and certain novel features of construction and arrangement,wliere by to produce knit goods containing, in addition to the usual interlooped knitting thread or threads, longitudinal or warp-threads and transverse or weft or filling threads, the said warpthreads and weft-threads serving to lessen the elasticity of such goods and other- Vwise operating to render them suitable for use in the manufacture of hydraulic hose andthe like, dress fabrics, die., and elsewhere in connections where the normal elasticity of ,knit goods is undesirable. i

The invention will be described iirst with reference to the accompanying drawing, in which latter I have illustrated the best embodiment of the invention which I have yet contrived.

The accompanying drawing shows in central vertical section a knitting-machine containing the said embodiment of the invention.

1 is a bed or base plate, which is mounted upon suitable legs or other supports.

2 2 are uprights, which, if desired, may be tubular, rising from the said bed or base plate near the edge thereof, and 3 is a plate supported by the said tubular uprights. Uprights 4, only one of whichv is shown, also tubular, if desired, rise from the said plate 3, and 5 is a top plate that is supported by the said tubular uprights 4.

6 6 are uprights, also tubular, if desired, rising from `the bed or base plate 1 near the center thereof. These uprights are shorter than the uprights 2 2 and they support at their upper ends the plate 61, to which is secured the fixed or non-rotating needle-cylinder 7, whichis applied thereto and connected therewith in any suitable and convenient manner.

S 8 are the needles working in the grooves ofthe said needle-cylinder, and 9 is a camcylinder or cam-carrier surrounding the said needle-cylinder and carrying the cams, which serve to actuate the needles S S in known manner.

2G is a ring that is connected with the camcylinder 9. Its V-shaped lower edge ts and turns in a V-shaped groove that is formed in the upper surface of the plate 6l. The outer edge of the said ring is formed with spur-teeth, the ring 26 being in the nature of a spur-ring or gear-ring. l

10 is a needle-dial supported above the needle-cylinder and provided with needles 11. 12 is the supporting-rod on the lower end of which the said needle-dial is pinned or otherwise secured. The upper end of the said rod extends up through a central opening in a cross-shaped support 13, which is located above the top plate 5, and the said upper end is screw-threaded to receive the adjusting` nut 14, which'latter rests upon the upper side of the cross-shaped support 13, so as to sustain the supporting-rod 12 and the parts which are mounted thereon. The said adjustingnut enables the height of the dial to be adjusted relatively to the upper end of the needle-cylinder. The cross-shaped support 13 is mounted on pillars 14 14, rising from the top plate 5.

15 is the dial-cam plate or carrier. It is sleeved upon the Vsupporting-rod 12, above the needle-dial 10, and carries the cams that engage with the dial-needles l1 to actuate the latter in known manner.

16 16 are guides for the knitting-threads, the said guides delivering the said knittingthreads to both sets of needles in unison, as required for the production of ribbed goods.

The foregoing parts are arranged and operated to produce rib-knittingv and are actuated as follows:

17 isa driving-shaft thaty is mounted in bearings beneath the bed or base plate 1.

18 is a bevel-gear thereon meshing with a bevel-gear 19, which is fast with a spur-gear 20, the said bevel-gear 19 and spur-gear 2O turning upon a stud 2l, which projects from the said bed or base plate 1. The spur-gear 20 meshes with two other spur-gears 22 and 23. Spur-gear 22 is on the lower end of an upright shaft 24, which extends upward IOO the cam-cylinder 9.

30 spectively.

through the interior of one of the central uprights G (3 and has applied to the upper end thereof a spur-pinion 25, which latter meshes with the spur-rin g 26, that is connected with By these devices the said cam-cylinder is rotated. The said spur-gear is fast upon the lower end of an upright shaft 27, which latter passes up through one of the tubular uprights 2. Just above the io intermediate plate 3 a spur-gear 28 is made fast upon the said shaft 27, which spur-gear meshes with and drives the gear-rin g 29. The latter is supported by the intermediate plate 3, concentric with the supporting-rod 12, and

is turned thereon by the said spur-gear 28.

The opening 291 through the said gear-ring 29 corresponds with the central opening 292 through plate 3. rlhe gear-ring29 is provided at opposite places thereon with supports 30 zo 30 for the spools or bobbins 31 31, which contain the knitting -yarns of which the foundation rib fabric is composed. The guides 16 1G for conducting the said yarns to the needles are attached to the said gear-ring 25 and extend downwardly therefrom, so as to 3 5 tact with the hub of the spur-gear 28. Above 'the top plate 5 the upright shaft 27 has fast thereon the spur-gear 33. The latter meshes with and drives a gear-ring` 34, mounted to turn on the said top plate 5 and having de- 4o pending arms 35 35, which connect or engage with the dial-cam plate or carrier 15 and serve to transmit motion to the latter.

3G 3G are supports placed opposite each other on the gear-ring 34 and havin g mounted 45 thereon the bobbins or spools 37 37 containing the inner set of weft or filling threads 371 371. The guides which deliver the said weft or filling threads to be bound in place in the fabric are shown at 372 372 and are attached 5o to the arms 35 35.

38 is a supporting-ring for the upper or inner set of spools or bobbins 39 39, containing warp-threads 391 391. The said ring is mounted on brackets 40 40, that are attached 55 to the top plate 5.

41 is a felt-covered ring supported by the brackets 42 42, which are attached to the said top plate 5, and around which ring the said warp-threads 391 are passed for the purpose 6o of producing the desired degree of tension therein.

43 is a ring attached by brackets 44 44 to the plate 5 and formed with saw-cuts or notches 45 45 to receive and guide the warp- 65 threads 391 391 adjacent to the point where they are bound into the fabric.

46 is a ring that is supported by brackets 47 47 from the intermediate plate 3, it serving as a support for the spools or bobbins 48 48, which contain the lower or outer set of warp-threads 481 481.

49 is a felt-covered tension-ring for the said outer set of warp-threads, the said ring 49 bein g supported by brackets 50 50 from plate 3, and 5l is a notched or kerfed spacing-ring for the said outer set of warp-threads, the said ring 51 being located adjacent to the place where the latter are bound into the fabric.

The inner or upper set of warp-threads pass down through the central opening 291 of the gear-ring 29 and are led from the spacingring 43 into the spaces between the dial-nee dles, while the corresponding weft or lilling threads 37 371 pass through the openings in the two gear-rings 34 and 29 and are laid within the circle described by the said warpthreads 391, that is, on the side of the said warp-threads 391 which is toward the center of such circle. The outer or lower set of warp-threads 481 481 pass from the spacingring 51 into the spaces between the cylinderneedles, and the weft or filling-threads 52 52 from the bobbins or spools 53 53, which are mounted on supports 54 54, carried by thc flange 55 of the cam-cylinder, are laid by their guides 521 521, which are carried by the said cani-cylinder, around the outside of the circle composed of the said outer or lower warpthreads 481 481. The knitting-threads are conducted to the needles, and also are engaged by the latter, between the two converging sets or circles of warp-threads. Thus the knitting is effected between the outer and inner sets or series of warp-threads. The said warp-threads thus are caused to lie against the opposite faces of the foundation rib fabric into which the knitting-threads are formed by the conjoint action of the two sets of needles, the said warp-threads lying in the spaces on each surface of the said foundation rib fabric which intervene between the Vertical lines or wales of loops on such surface. The said warp-threads are overlaid on each surface of the fabric bythe weft or filling threads, and the said weft or lling threads in turn are bound to the said foundation rib fabric by the loops which are formed by the needles in the knitting thread or threads, the said loops being drawn by the action of the said needles around and over the said weft or filling threads.

The use of the two sets of warp-threads, as will be perceived, renders it necessary to support the dial and dial-cam, as well as to transmit movement thereto, wholly from above, and by means of devices passing downwardly within the upper converging series of warpthreads, and also to support and actuate the needle-cylinder and cam-cylinder by means of devices extending upwardly from below entirely within the lower converging series of warp-threads, the employment of lugs or the like to retain the needle-dial from rotating and to cause the dial-cam carrier or plate ICO IIO

IZO

to rotate in unison with the cam-cylind er being precluded by the presence of the warpthreads. The open gear-ring 29 is of great importance in permitting the upper series of warpthreads to proceed uninterruptedly to the place at which they are bound to the ribbed foundation fabric which is produced by the action of the two sets of needles upon the knitting-threads.

As will be obvious, the construction of the supporting-framework, as well as the details of the operating or driving` devices and connections, may be varied as desired.

I claim as my inventionl. An organized knitting-machine having two sets of needles, and means to deliver knittingyaru to the said needles, whereby to produce a foundation rib fabric, means lto deliver a separate set of warp-threads upon each side of the said foundation rib fabric between the vertical lines of stitches thereof, and means t-o lay7 weft or filling threads outside the said sets of warp-threads in position to be bound by the loops of knitting-yarn that are formed by the needles, substantially as described.
